I was there last spring I think like april 15 or something, right under the bridge,
fished for about 3.5 h and not even a bite, the current was fast and strong,
there were guys in a jet boat fishing up the stream all morning caught only 2 12" bows... I was a bit disappointed but happy enough cause all water around edmonton was still under 6" of ice
Report back if you go there next week,
Cheers !
